<h1 class="topictitle1">In GaussDB (DWS) 8.1.3, a Backup Job Fails Due to GaussDB (DWS) Software Processing Exceptions</h1>
<div><div class="section"><h4 class="sectiontitle">Fault Symptom</h4><p>In GaussDB (DWS) 8.1.3, a backup job fails to be executed when the client is installed on the production host and an independent physical server, and a message is displayed indicating that the Roach command fails to be executed.</p>
</div>
<div class="section"><h4 class="sectiontitle">Possible Cause</h4><p>After data backup is complete, the upload process is started before the GaussDB (DWS) backup process exits completely. As a result, service processing conflicts.</p>
</div>
<div class="section"><h4 class="sectiontitle">Suggestion</h4><ol><li><span>Log in to the node where the backup command is delivered.</span></li><li id="EN-US_TOPIC_0000002199963941__li1047516520486"><a name="EN-US_TOPIC_0000002199963941__li1047516520486"></a><a name="li1047516520486"></a><span>Run the following command to go to the log file directory.</span><p><pre class="screen">cd /opt/DataBackup/ProtectClient/ProtectClient-E/slog/Plugins/GeneralDBPlugin/</pre>
